ATD-THOR Dummies

High Fidelity FE Dummy Models for CAE Vehicle Safety Analysis

In 2019, by contractual agreement with ATD-Models GmbH, CDH AG acquired the rights to market, distribute and support ATD-THOR dummy and finite element (FE) impactor models in North America and Japan. ATD-MODELS GmbH is a specialist in the development of high-quality FE models for vehicle safety analysis. The company was founded in 2009 by experts with years of experience in dummy development and occupant-safety simulation. ATD-MODELS GmbH develops highly accurate FE models in close cooperation with the German and other world-wide automobile industry partners. ATD FE models are used in the virtual development process for occupant and pedestrian protection engineering calculations.

THOR is the acronym for Test Device for Human Occupant Restraint. The ATD-TH50 and ATD-T350 are FE-models based on the THOR 50% Male ATD hardware and represent the most advanced frontal impact models in the 50% man dummies segment. The THOR has improved life-like properties and a significantly expanded measurement method compared to the standard Hybrid III 50% male dummy.
THOR 50% is therefore the latest model in the field of highly developed frontal impact dummies and it is used, for example, in the US NCAP and Euro NCAP occupant protection.

Following SBL-B versions of the THOR 50% Male ATD are available:

  • ATD-TH50 with Thor-LX legs in accordance with US NCAP and C-NCAP
  • ATD-T350 with HII legs in accordance with Euro NCAP
  • ATD-TH50-R is a reclined version of ATD-TH50 with Pelvic/abdomen modification

ATD-MODEL of the THOR 50% Male Dummy

Based on the NHTSA drawings, ATD-MODELS GmbH developed the FE model ATD-TH50. The experience of the set up and enhanced development of the ATD-H3 models were incorporated into the model. Therefore, users of this model will quickly recognize the familiar structure and system and will be able to use the ATD-TH50 easily.

Some characteristics of the ATD-TH50 are:

  • Signal designations according to ISO-MME
  • Easy introduction to handling thanks to the familiar model structure analogous to ATD-H3 models
  • Understanding of structure through realistic mapping of the geometries

Application:

  • Foreseen for future U.S. NCAP oblique impact test

ATD-TH50

ATD MODEL of the THOR 50% Male Dummy with Hybrid III 50% legs

The ATD-T350 is based on the ATD-TH50, which is also available. Instead of the Thor-LX lower legs, the legs of the ATD-H350 (Hybrid III 50%) are installed in this model.

Some characteristics of the ATD-H305 are:

  • Lower legs of the ATD-H350
  • Knee slider of the ATD-H350
  • Can be used in the same way as the ATD-TH50

Application:

  • EuroNCAP
    - MPDB
  • C-NCAP
    - MPDB (From Jan 2022 on)
  • A-NCAP
    - MPDB

 ATD-T350

ATD MODEL of the THOR 50% Male Dummy with Pelvic/abdomen modification

The ATD-TH50-R is based on the ATD-TH50. This model contains modifications to the THOR-50M for improved usability in reclined postures expected in autonomous vehicles. The hardware design is being realized by Cellbond and The University of Virginia (UVa) in a collaborative project funded by NHTSA. For further information please click here.
The FE-model is developed by ATD-MODELS in close collaboration with Cellbond providing information on the hardware design as proposed to NHTSA.

Some characteristics of the ATD-TH50-R are:

  • Reshaped flesh contours at pelvis – thigh interface
  • Introduction of unified abdomen
  • Addition of third flexible element in spine
  • Use similar to ATD-TH50
  • Signal designations according to ISO-MME

Application:

  • Research on occupant safety assessment of automated / driverless cars

ATD-TH50-R

ATD MODEL of the THOR 05% Female Dummy

The ATD-TH05 is currently in development. The model will be based on the current NHTSA Drawings and set-up using already established structures of the ATD-MODELS dummy portfolio. A first version is expected to be available this year. The ATD-TH05 is developed in close collaboration with Cellbond the developer of the hardware.

Application:

  • Research on occupant safety assessment

ATD-TH05

ATD Models Features and Advantages

Advantages to Users:

  • Systematic title nomenclature refers to the assembly groups
  • Prefix in each title description allows a fast adjustment to the nomenclature of the load case
  • Numeration not overlapping the assembly groups
  • Advantage in pre and post processing
  • Allows selection of assembly parts and groups
  • Each assembly group close defined for itself
  • Definition regarding the master, e.g. contacts relate to the assembly group
